BOLTING-REEL.

SPECIFICATION forming part of Letters Patent No. 380,527, dated April 3,1888.

Application filed May 14, 1887. Serial No. 238,235. (No model.)

To (ZZZ whom 2'25 may concern.-

Be it known that I, ilIACONIUS SHANER, a citizen of the United States,residing at Beaver Falls, in the county of Beaver, in the State ofPennsylvania, have invented certain new and useful Improvements inBolting- Reels, of which the following is a specification.

My improvements relate to a reel for bolting flour, meal, and likematerials, in which the material being bolted is subjected toair'suction for the removal of the lighter impurities and is fed intothe reel. by automatic scoops or con veyers which may discharge belowthe shaft of the reel.

To these ends my invention consists in certain details of constructionhereinafter fully described and claimed.

In order that my invent-ion may be fully understood, I will firstdescribe it with reference to the accompanying drawings, in which-Figure I is an elevation of the head of my improved reel and section ofcasing and feedbox on line I I, Fig. Ill. Fig. II is a verticaltransverse section of the reel and easing on line 11' II, Fig. III. Fig.III is a vertical longitudinal section thereof on line III III, Fig. I

1', part of the visible wings being broken away and showing them cut offat an angle, the bolting-cloth being shown. beyond such broken portion.

1 may represent a casing of ordinary shape. 2 is the feed-box, suppliedwith middlings, meal, or flour through spout'3.

4 is the cloth of the reel, carried by skeleton 5 from shaft 6 incustomary manner. The shaft is mounted in the ends of the casing 1 andis driven in any manner.

The head 7 of the reel is made imperforate. Meal is carried from thefeed-box 2 into the reel by means of scoops or elevators 8, open at bothends and shaped so as to discharge material on the cloth, preferablybelow the shaft. These scoops are arranged spirally relatively to thereel, and are supported on the outside thereof, the outer ends or monthsof which are arranged at the outer end of the reel, while their innerends, by reason of the scoops being arranged spirally, deliver thematerial toward the other end of the reel.

The tail 9 of the reel is open around the shaft 6 to correspond with anopening in the side of a vertical air-trunk, 10, arranged between thetail of the reel and the end of the casing and communicating with theeye of an exhaust-fan, 11. This fan takes up the lighter impurities fromthe material and blows them away to the dust-room, the air to supply thefan coming partially through the scoops 8, but mainly through the meshesof the cloth, where it assists the bolting action materially by keepingthe meshes clear. To supply air through the casing for this purpose, anydesired number of holes, 12, are provided in the sides of the easingnear the top, said holes having suitable valves for regulating thesupply along the entire length of the casing. The draft can also beregulated by cut-off slides, either in the airtrunk or at the fan. Toprevent air from passing into the trunk 10 between the latter and thetail of the reel, a packing, 13, is provided around the opening in theend of the reel. Preferably sheep-skin with the wool on is used, thewool, which is turned outward, affording a soft tight cushion havinglittle friction.

At bottom the air-trunk 10 has a valve, 10 which may be opened to allowsuch heavy matter as has dropped therein after entering the trunk to bediseharged.

I guard against the carrying away of any valuable part of the materialby the fan, and at the same time increase the effectiveness of thebolting operation, by providing wings 15 16, arranged in pairs, runningfrom head to tail of the machine. Of these wings, 15 is flat and isarranged to receive the material as it falls on the rising side of thereel and throw it back on the cloth, thus spreading it evenly over thelatter. The other wing, 16, tightly fixed to wing 15 near the cloth,projects within the inner edge of the wing 15 of the adjoining pair, andis then turned outward to such an extent as to allow a narrow passagebetween the two wings for the passage of the lighter impurities as theyare drawn off by the fan, and afford a trap, 17, which catches any heavymaterial falling toward the center, and at the descending side of thereel discharges it onto the cloth.

It will be seen that as the material flows in a thin sheet from thewings to the cloth it is subjected to a blast of air passing through thecloth and a separation is thus made the entire length of the reel. Theimpurities drawn through the openings between the wings are prevented bythe overlapping of the Wings from returning until they are dischargedfrom the reel.

The tailings are discharged through openings closed by valves 18, hingedat 19 and having stops 20 extending radially from and secured by nuts 20on the periphery of the reel and located entirely at the free ends ofthe gravity-valves for limiting their fall. These valves openautomatically on the lower side of the reel to discharge the offal, andclose automatically at top to stop the flow of air into the reel.

The usual oonveyers, 21 22, and cut-off slides 23 are provided at thebase of the casing for keeping the screenings and offal separate andconveying them away.

Having thus described my invention, the

following is what I claim as new therein and desire to secure by LettersPatent:

1. The combination of a rotary cloth or screen, a suctionfan connectingwith the interior thereof, and wings arranged within the screen inpairs, the members of each pair being close together at their outer endsand slightly separated from the adjoining pairs at their inner ends andprojecting one beyond the other at said inner ends, substantially as andfor the purpose set forth.

2. The combination of a rotary cloth or screen, a suction-fan connectingwith the interior thereof, and wings arranged within the screen inpairs, one member of each pair projecting beyond the inner end of theadjoining member of another pair and being there provided with a trap,substantially as and for the purpose set forth.
